◉ What is the difference between FTTN and FTTC. Answer: FTTC is
allowed a smaller number of RF amplifiers between the optical fiber and
the customer premises
◉ Which of these components is used in a PON(Passive Optical
Network). Answer: Optical Splitters
◉ Which type of Star topology used in a PON(Passive Optical Network)
places the PON splitters into FATS(Fiber Access Terminals) located deep
in the network and closer to the customer premises than the centralized
split. Answer: Distributed Star
◉ Which element of a PON(Passive Optical Network) uses a Bragg
grating filter. Answer: OLT(Optical Line Terminal)
◉ Which element of a PON(Passive Optical Network) uses Patch
Panels. Answer: ODN(Optical Distribution Network)
◉ What is it about Radio Frequency over Glass(RFoG) that made
broadband cable operators envision using it to make a seamless
transition from the legacy hybrid/fiber coax(HFC) architecture over to a
,gigabit-capable passive optical network (GPON) or Ethernet passive
optical network (EPON). Answer: RFoG can operate in parallel with
GPON or EPON, which eliminates the need for any downtime during
the transition
◉ How are optical splitters used in the forward path. Answer: In the
forward path, optical splitters are used as passive branching devices that
divide an optical signal across multiple output fibers
◉ Which of the following describes a fiber pigtail. Answer: Fiber-optic
cable with pre-connectorized ends
◉ Heat Shrink tubing is installed over the fusion-splice to strengthen
and protect it. When should the heat shrink be installed on the fiber.
Answer: Before stripping the plastic coating from the fiber
◉ Which of the following is a method for controlling expectations.
Answer: focus on the bigger picture rather than smaller tasks
◉ Which of the following best describes stereotyped thinking. Answer:
Presuming that all members of a group have certain characteristics
◉ The attribute of being "active" as a critical thinker means. Answer:
You observe and take notes relevant to the issue
, ◉ What kind of reasoning is described as applying a general statement
that you know to be true to a new situation. Answer: Deductive
◉ It is essential to pay attention to warning signs of stress overload.
Poor attitude is one of the behaviors that may indicate that you are
overstressed. What are the symptoms of poor attitude behavior. Answer:
A significant change in attitude with a noticeable movement toward
negative, hostile, cynical, or paranoid thoughts
◉ You are at a customer's house and you are asking the customer
whether the problem is intermittent or constant. Which step are you
using from the six-step troubleshooting process. Answer: Identifying the
problem
◉ Why should you take the time to take notes and accurately record data
at each job location. Answer: Notes and recorded data are tools that can
help you accurately remember events at a site that can help you
determine a plan of action or evaluate the decisions you made
◉ You are at a customer's home and you believe you have solved the
problem. When you check to be sure there are no new problems, which
step are you using. Answer: Verifying the Solution
◉ To break the habit of a negative self-talk cycle. Answer: Tell yourself
"not now" and move onto a positive thought whenever negative thoughts
occur
